General Description
TS2580 Series are step-down switching regulators with all required active functions. It is capable of driving 2A
load with excellent line and load regulations. These devices are available for adjustable output version. TS2580
series operates at a switching frequency of 52kHz thus allowing smaller sized filter components than what would
be needed with lower frequency switching regulators. It substantially not only reduces the area of board size but
also the size of heat sink, and in some cases no heat sink is required. The ±4% tolerance on output voltage within
specified input voltages and output load conditions is guaranteed. Also, the oscillator frequency accuracy is within
±10%. External shutdown is included. Featuring 100µA (typical) standby current. The output switch includes cycle-
by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
